First 3D Printed House to Be Built In Amsterdam

“The building industry is one of the most polluting and inefficient industries out there,” Hedwig Heinsman of Dus Architects tells The Guardian's Olly Wainwright, “With 3D-printing, there is zero waste, reduced transportation costs, and everything can be melted down and recycled. This could revolutionise how we make our cities.”

Working with another Dutch firm, Ultimaker, Dus Architects have developed the KamerMaker (Room Maker), a 3D Printer big enough to print chunks of buildings, up to 2x2x3.5 meters high, out of hotmelt, a bio-plastic mix that's about 75% plant oil. The chunks can then be stacked and connected together like LEGO bricks, forming multi-story homes whose designs can be adapted according to users' needs/desires. For Dus' first project, they've taken as inspiration the Dutch canal house, replacing hand-laid bricks with, in Wainwright's words, "a faceted plastic facade, scripted by computer software."

So far, only a 3m-high, 180-kg sample corner of the future canal house has been printed; moreover, the blocks will need to be back-filled with lightweight concrete, meaning it's not yet as biodegradable as its creators would like. However, its game-changing potential is already provoking much interest in the public; over 2,000 people have come to visit the site, including Barack Obama.
